Earth’s third-warmest year on record occurred in 2025, reinforcing a decades-long pattern of rising global temperatures. This warming trend is increasingly reflected in regional weather patterns across the United States, particularly in Texas, where hotter summers, prolonged droughts, and heavier rainfall events are becoming more common.

A 2024 report from Texas A&M University highlights how these shifts are already reshaping weather conditions across the Lone Star State. The assessment analyzes climate and weather data from 1900 through 2023 and projects likely trends through 2036.

Its findings suggest that extreme weather in Texas is not only increasing but also becoming more hazardous for communities, infrastructure, and the economy.

A Rise in Extreme Heat
One of the most dramatic changes is the increasing frequency of extreme heat events. Summer temperatures in Texas have climbed back to levels not seen since the early 20th century, and projections suggest they will exceed those historic highs within the next decade.

Triple-digit temperatures are becoming far more common. In the 1970s and 1980s, most parts of Texas experienced relatively few days above 100°F in a typical year. By 2036, those days are expected to occur about four times as often, especially across North, Central, and West Texas.

Houston reflects that broader trend. Five of the 10 years with the most 100-degree days on record in the city have occurred since 2000, according to records dating back to the late 1880s.

The summer of 2023 was Houston’s hottest on record, surpassing even the historic heat of 2011. While short-term cold snaps still occur, climate data suggests extreme summer heat will become more frequent in the years ahead.

Heat waves are also starting earlier in the year and lasting longer. As of 2024, the average length of heat-wave season in the United States has increased by 46 days since the 1960s. Their frequency has also increased steadily, rising from an average of two heat waves per year in the 1960s to about six per year in the 2010s and 2020s.

Energy Grid Strain
Heat waves occurring earlier in the year and more intensely place increasing pressure on the state’s electricity system. When temperatures spike early in the summer, households and businesses simultaneously increase air-conditioning use, pushing electricity demand close to record levels.

In recent summers, record-breaking electricity demand has repeatedly tested grid capacity. Energy experts warn that if heat extremes continue to intensify, maintaining grid reliability will require expanded generation capacity, improved energy efficiency, and greater integration of renewable energy and battery storage. Fortunately, Texas has already made strides in these areas of concern.

Texas continues to lead the nation in clean energy adoption and grid modernization, particularly in wind and solar power. With more than 40,000 megawatts (MW) of wind capacity, the state ranks first in the country in wind-powered electricity generation, supplying up to 35% when blowing and as low as 0%. Much of this growth was driven by the state’s Renewable Portfolio Standard (RPS), which requires utility companies to develop renewable energy in proportion to their market share. The policy originally set a goal of generating 10,000 MW of renewable capacity by 2025, but Texas surpassed this target years ahead of schedule due to rapid investment and expansion.

Solar energy is also growing quickly. Texas has officially overtaken California as the country’s. leader in utility-scale solar, according to recently released data from the U.S. Energy Information Administration. With over 37 GW of capacity, Texas now leads in new solar installations, supported by large-scale solar farm development and favorable policies that continue to diversify the state’s energy mix.

To build a more resilient and cost-effective power system, Texas is working to integrate wind and solar generation while strengthening grid reliability. Efforts include regulatory reforms, mandates for improved power infrastructure, and the deployment of renewable energy storage solutions. A recent report from the Solar Energy Industries Association indicates that Texas is on track to surpass California this year as the nation’s leader in energy storage capacity, driven largely by the rapid growth of battery storage facilities across the state. Alongside renewable expansion, the state also added 3,410 MW of natural gas–fueled power in 2024 to support growing electricity demand.

Economic Consequences
Extreme heat also has measurable economic impacts. For every 1-degree increase in the average summer temperature, Texas’ annual nominal GDP growth rate slows by about 0.4 percentage points. Because Texas already experiences hotter summers than most of the country, rising temperatures affect the state’s economic growth about twice as much as they do in the rest of the United States. Additional warming compounds the strain on productivity, infrastructure, and energy costs.

Some industries are more sensitive to heat than others. Construction, agriculture, manufacturing, and outdoor services often experience productivity losses during prolonged heat waves.

The effects were already visible during the record-breaking summer of 2023, when cities such as Houston, Dallas, and El Paso experienced prolonged stretches of triple-digit temperatures. Surveys conducted by the Federal Reserve Bank of Dallas found that roughly one-quarter of businesses responding to the Texas Business Outlook Surveys reported reduced revenue or production because of the heat.

The hardest-hit sector was leisure and hospitality, where outdoor activities and tourism often decline during extreme temperatures. However, businesses across manufacturing, retail, and services also reported disruptions.

Environmental and Infrastructure Stress
In addition to heat, there are growing risks related to drought, wildfire conditions, and urban flooding.

Extended heat waves tend to worsen drought conditions by increasing evaporation and reducing soil moisture. Lower water levels in lakes and reservoirs can lead to water restrictions for cities and agricultural producers, especially in regions that rely heavily on surface water supplies.

Dry conditions also increase the likelihood of wildfires, particularly across West Texas and the Hill Country. Strong winds, dry vegetation, and extreme heat can quickly turn small fires into fast-moving blazes that threaten homes, infrastructure, and ecosystems.

At the same time, Texas is experiencing an increase in severe rainfall events, which can overwhelm drainage systems in rapidly growing urban areas. Cities with large amounts of pavement and development are especially vulnerable to flash flooding when heavy rain falls in short bursts.

Along the Gulf Coast, rising sea levels are adding another layer of risk. Communities near Galveston Bay and other low-lying coastal areas face increasing threats from storm surge and high-tide flooding.

Preparing for a Hotter Future
Climate experts emphasize that over the next decade, Texans are likely to face more frequent heat waves, higher energy demand, and greater environmental stress.

Adapting to these changes will require a range of responses, including strengthening infrastructure, expanding water management strategies, improving urban planning, and enhancing emergency preparedness for extreme heat and flooding.

While the challenges are significant, understanding these trends now gives policymakers, businesses, and communities time to prepare. As the state’s population and economy continue to grow, resilience to extreme weather is an increasingly important priority for Texas in the years ahead.

A View From HETI

If you are a Houston native or have lived in the city since the 1980s, you likely remember when a 100-degree day was so rare it made the local news. There were heat advisory warnings, with special attention to the midday hours, because the heat exposure carried with it risks like dehydration, heat stroke and extreme exposure to UV rays.

In this new era for our city and state, 100-degree days are becoming more common. Our local weather forecasters still report on the occurrence, but we are no longer able to restrict our activities as heavily.

The climate has changed rapidly, and Texans are navigating our collective response to the increased heat that has serious implications for our health, energy supply, economy and regional life.

Houston Has Always Been Hot, But This Heat is Different

Houston has expanded exponentially in the last few decades, doubling its population from roughly 1.4 million in 1976 to 2.4 million today. When we account for the growth in the surrounding suburbs, the population boom nearly quintuples.

Houston and the surrounding suburbs now total nearly 7 million people, a huge population increase that brings greater demand for energy. This demand impacts our infrastructure, energy availability, consumer costs, workforce productivity and water supply significantly. With these additions comes more asphalt and fewer trees. With less tree cover and green space, heat gets trapped, increasing temperatures in the city.

We are not just inheriting rising temperatures; we are also building hotter cities.

100-Degree Days and The Texas Grid

I have written before about our grid capacity, changes facing Texas, and the strain that we have seen on the grid. While redundancies in the Texas grid are improving, the pace of this change continues to pose challenges for our area.

The extreme heat has now made air conditioning mandatory for a greater percentage of days during the calendar year. AC units (large and small) are no longer cycling on and off as they are designed to run; instead, most systems are running continuously to meet the needs of Texans.

Daily activities and devices, including remote work, the AI boom, physical exercise, children’s playtime, charging multiple devices, and streaming entertainment, require much more cooling than in previous generations, producing a much larger demand on the grid.

Additionally, the way Houstonians live at home has also changed. Homes across America are much larger on average than they were in the 1980’s. Also, with the rise of remote work, there is a greater need for all-day electricity in each individual household. These factors, combined with the exponential increase in the number of devices and appliances used in households, significantly affect energy demand in our region.

Of course, we’re also seeing massive usage of electricity from large business users (warehouses, data centers, and more), including empty office buildings as return-to-office is slower than expected post-pandemic.

Heat is Not the Only Culprit

As Houston is a coastal city, we not only have to contend with 100-degree temperatures, but humidity also adds an extra layer of complexity to our climate. Thanks to the humidity, temperatures stay elevated for longer periods, meaning everything is retaining heat at a higher rate and for longer than ever before.

The heat never really leaves us anymore, as we don’t have cooler nights to help balance these very hot days. The compounding effect of extreme temperatures and high humidity makes energy demand higher in our region than in places like the New Mexico desert.

Economic Impact on Our Region

Extreme heat hits Texans’ wallets long before a weather alert ever pops up. When temperatures stay above 100 degrees for days at a time, air conditioners are basically working overtime, which sends electricity bills climbing.

And the harder those systems run, the more wear and tear homeowners end up dealing with, usually at the worst possible time, like the middle of July when a boom of AC units decide to quit at once. Meanwhile, roads, transformers and other infrastructure are all under more stress than they were originally built for.

There’s also a much bigger ripple effect that people don’t always think about. When it’s dangerously hot outside, construction crews, energy workers, landscapers, and other outdoor industries simply can’t operate the same way, which slows productivity and raises safety concerns.

Cities are also spending more money on cooling centers and heat-related emergency response, and over time, all of those rising costs have a way of showing up somewhere, whether that’s insurance rates, utility costs or the price communities pay to keep up with extreme weather.

The Opportunity for Houston

Texas is becoming a real-time test case for what happens when extreme heat, rapid growth, and massive energy demand all hit at once. While problematic, it also creates a huge opportunity for Houston and the Texas energy sector to lead. If there’s any place equipped to determine what the future of energy resilience looks like, it’s the city that already powers so much of the world’s energy conversation.

And the solution isn’t just “create more electricity.” It’s about building a smarter, more flexible system overall with better grid technology, battery storage, stronger infrastructure, more efficient building, and energy systems that can handle these extreme weather swings without everything feeling stressed at once. The reality is that a lot of what Texas figures out over the next few years could become the blueprint for other cities and states across the country.

Houston is already testing some of these smarter resilience strategies, such as microgrids, stronger substations, and more flexible energy systems designed to keep critical facilities running during major storms or outages. The goal is simple: build a grid that can take a hit without everything feeling strained all at once.

Going Forward

Hotter days are here to stay. We can’t stop our lives amid the extreme heat, so we have to find ways to adapt and we have to do it quickly. If there’s one thing Texas has always done well, however, it’s innovate under pressure. The communities, companies and energy leaders that move fastest now won’t just be responding to the future, they’ll be helping define it.
